About this product
The PT4103 is a step-up DC/DC converter that drives up to 8 white LEDs in series from a single Li-ion cell with constant current. A single external resistor sets the LED current between 5 mA and 20 mA, and dimming is possible with a DC voltage or a PWM signal. Its low 104 mV feedback voltage helps keep power loss and efficiency losses low.

Frequently asked questions
What is the price of PT4103 Step-Up White LED Constant-Current Driver SOT23-6 in Egypt?
PT4103 Step-Up White LED Constant-Current Driver SOT23-6 currently costs 17.1 EGP in Egypt.
Where can I buy PT4103 Step-Up White LED Constant-Current Driver SOT23-6 in Egypt?
PT4103 Step-Up White LED Constant-Current Driver SOT23-6 is available from UGE. Compare the offers above to find the best price.
How do I set the LED current?
An external sense resistor sets the current. Using the 104 mV feedback voltage, the resistor is approximately 0.104 V divided by the desired LED current, for example about 5.2 Ω for 20 mA. Confirm the exact formula and resistor power rating in the datasheet.
Can I dim the LEDs?
Yes. Dimming is supported with either a DC voltage or a PWM signal applied to the dimming input, as described in the datasheet.
